The Guildford was a ship of 521 tons built at the Thames in 1810. According to Bateson (1983, p. 231):

The Guildford was one of the best known convict ships. . . . In eight voyages as a convict ship the Guildford conveyed over 1,500 male prisoners to Australia for the loss of about a dozen men on the passage, the record of her passages being as follows: . . .

1820 Portsmouth to Sydney 139 days . . .

The Guildford had the same master for its first seven voyages, Magnus JOHNSON. Robert HARRISON was her master on her eighth voyage. "Johnson was a prudent and conscientious master, and he treated the convicts humanely" (Bateson, 1983, p. 232).

On her fourth voyage, the Guildford sailed from Portsmouth on 14 May 1820, passing via the Cape to Sydney, where she arrived on 30 September 1820, and then on to Hobart where she arrived on 28 October 1820, 167 days after leaving Portsmouth. Her surgeon on this voyage was Hugh WALKER. She carried 190 male convicts, of which one was landed at Sydney and the remaining 189 were landed at Hobart Town.
